To all whom it may concern;

Be itknown that I, JAMEs A, QAnNEiT, a cltizen of the United States,residing at Aurora, in the connty'of'Kane and State of ,Illinois, haveinvented" certain new and use ful Improvements I 1n Brake; Operating,Mechanlsm, oi whlch the followlng 1s a specification.

This invention relates to improvements in, brake operating mechanism,The object of l this inventionis to provide a brake operating mechanismwhich may be utilized with V freight cars or the like and hich comprisesin combination with a vertically. located ro-l tat ng brake shaft, ahorizontally located hand OPGPtLtlllgdOVGl 1nCOInblnittlOlTWlth a Iratchet Wheel attached to the brake shaft together with a coacting pawlandja detent.

Still another object is to provide mechanism of the. character describedabove so arranged and con structed that proper opera tion-ot the handlever Will operate to Wind the brake shatoto apply the brakes andproperreverse:movement tliereofwlien desired willeoperate to positivelydisengage thedetent and pawl.

vice with more or less particularity, I do not wish to be restricted tosuch showing or description beyond the scope of the appended claims.

That I claim is 1. A device of the class described comprising a ratchetvmember substantially horizontally arranged, an operating lever alsosubstantially horizontally arranged, a pawl pivotally attached to saidlever and normally engaging said ratchet member where by proper'rotationof said lever will efl ect rotation in one direction of said ratchetmember, and a detent arranged to prevent reverse rotation of saidratchet, said pawl being arranged to positively disengage said detentupon proper movement of said lever.

2. In combination with a substantially vertical brake operating shaft, asubstantially horizontally arranged ratchet member secured thereto, anoperating leverrotatably mounted thereon, a pawl pivotally mounted onsaid lever and normally engaging said ratchet member, and a detentnormally engaging said ratchet member, said pawl being arranged to coactwith said ratchet member and said detent member upon proper movement ofsaid lever to disengage itself and 3. In combination with asubstantially vertical brake operating shaft, a substantiallyhorizontally arranged ratchet wheel secured thereto, said ratchet wheelbeing provided with ratchet teeth on one side thereof, an operatinglever rotatably mounted adjacent said ratchet wheel, a pawl p1votallyattached to said lever and normally engaging said ratchet wheel toeffect rotation of said wheel in one direction upon proper. movement ofsaid lever, a detent member pivotally mounted adjacent said ratchetvwheel and normally engaging the same to prevent reverse rotationthereof, and means associated with said pawl and detent for effectingthe disengagement of both said pawl and detent with said ratchet wheelupon proper movement of said lever.

4. In combination with a vertically arranged brake shaft, a horizontallydisposed ratchet member mounted thereon, a leverrotata'bly mounted onsaid shaft, a pawl aotuated by said lever and normally engaging saidratchet member toeifect rotation thereof on proper movement of thelever, a detent. arranged normally to engage said ratchet member toprevent reverse rotation thereof, said pawl and detent having partsadapted to coact upon proper movement of the lever to effect thedisengagement of both the pawl and detent with said ratchet member, andmeans to limit the disengaging movements of said pawl and detent.

' 5. 'In'combination with a vertically arranged shaft, a horizontallydisposed ratchet member mounted tl iereon and having teeth on one sidethereof, an operating lever rotatably mounted on said shaft, a pawlpivotally mounted on said lever and actuated by gravity normally toengage said teeth, a bracket extending upwardly adjacent said shaft, anda detent pivotall mounted on said bracket and actuated by gravitynormally to engage said teeth, said pawl and said detent carrying partsadapted to engage each other upon proper movement of said lever to moveboth said pawl and detent out of engagement with said teeth, said detenthaving a part adapted to engage a plane surface of said ratchet memberto limit the disengaging movements of said pawl and detent.

6. In combination with a vertically arranged shaft, a horizontallydisposed ratchet member having teeth on one side thereof, an operatinghandle rotatablv mounted on said shaft, a pivotally mounted pawlactuated by said lever, and a detent pivotally mounted adjacent saidratchet member, said pawl and detent being actuated by gravity normallyto engage said ratchet member and having parts adapted to coact witheach other upon proper movement of the lever to effect the disengagementof both the pawl and detent with said ratchet member.

7. In combination with a substantially vertically located brakeoperating shaft, a ratchet wheel attached thereto, an operating leverrotatably mounted adjacent said ratchet wheel, the latter being providedwith ratchet teeth on the side thereof adj acent said lever and beingfurther provided with a peripheral flange, a pawl pivotally mounted onsaid lever, said pawl having a portion adapted to normally engage saidratchet teeth and also a disengaging portion, a detent pivotally mountedadjacent said ratchet wheel, said detent being provided with a portionnormally engaging said ratchet teeth, and a cam portion, said detentbeing further provided with an extended arm. said disengaging portion ofsaid pawl being adapted to coact with said cam portion of said detentand said peripheral flange of said ratchet wheel to effect disengagementof said pawl. and detent fromsaid ratchet teeth upon proper movementofsaid operating lever, said extended arm of said detent operating tolimit said disengaging movement of said pawl and detent by contactingwith said peripheral flange of said ratchet wheel.

8. In combination with a substantially vertically located brakeoperating shaft, a ratchet wheel attached thereto, an operating leverrotatably mounted adjacent said ratchet wheel, the latter being provided-with ratchet teeth on the side thereof adjaportion adapted to normallyengage said ratchet teeth and also a disengaging portion, a detentpivotall mounted adjacent said ratchet Wheel, said detent being providedwith a portion normally engaging said ratchet teeth, and a cam portion,said detent being further provided with an extended arm, saiddisengaging portion of said pawl being adapted to coact with said camportion of said detent and said peripheral flange of said ratchet Wheelto effect disengagement of said pawl and detent from said ratchet teethupon propermovement of said operating lever, said extended arm of saiddetent operating to limit said disengaging movement of said pawl anddetent by contacting with said peripheral flange of said ratchet wheel.

9. In combination with a car body and a substantially verticalbrake-shaft rotatably secured thereto and extending above the roofthereof, a substantially horizontally arranged ratchet wheel mounted onsaid I shaft above said roof, teeth on the under a face of said Wheel, aperipheral flange on said wheel extendlng slightly beyond sald teeth,and means arranged between said wheel and said roof for engagement witha pawl adapted to coact with said teeth to rotate said shaft, said teethbeing positioned inwardly of the outer periphery of said wheel toprovide a flange whereby said wheel may be rotated by hand independentlyof said pawl.

In testimony whereof, I have subscribed my name. 7
